Members of Maryland's congressional delegation asked General Motors Co. on Wednesday to reconsider its decision to end operations at its White Marsh plant — or at least return more than $100 million in grant money it received for the facility.... Delegation members, including Rep. C.A. Dutch Ruppersberger — the Baltimore County Democrat whose district includes the plant — met privately in Washington with GM CEO Mary Barra.... Afterward, Ruppersberger released a joint statement with several delegation members, urging Barra to reconsider and asking the automaker to return about $115.5 million in federal, state and local grants dedicated to the White Marsh operation.... “If it insists on laying off the employees who helped it rebound from near-bankruptcy, GM should return these grants to the taxpayers by providing re-training and new opportunities to affected employees,” the statement said. “Additionally, absent a change of heart, we asked Chairman Barra to help find a new tenant for the facility that offers a manufacturing future for the community of White Marsh.” ... The statement was signed by Ruppersberger, U.S. Sens. Ben Cardin and Chris Van Hollen, and Reps. Elijah Cummings, Steny Hoyer and John Sarbanes.
